WIRE MATTRESS.

Specification of Letters Patent.

Patented June 11, 1918.

Application filed January 14, 1918. Serial No. 211,816.

To all whom it may concern:

Be it known that I, FRANK P. DOOLEY, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in which the following is and exact description.

My invention relates to wire mattresses of a construction employing a rectangular frame, a plurality of coiled springs disposed perpendicularly to the plane of the frame and arranged in spaced apart rows that extend longitudinally of the frame and which springs are also arranged in rows that ex tend transversely of the frame, end coils of the springs being substantially in the plane of the frame, and substantially parallel pairs of tie rods margining opposite sides Wire Mattresses, of

of the spaces between parallel rows of springs and secured at their sides of said frame.

By means of my invention "I have dispensed with other tie rods that hitherto have been employed at right angles to the aforesaid tie rods. I accomplish this result by forming the tie rods of each pair with loops that extend across from one row of springs to the adjacent row of springs, each loop having its base and bight respectively in hinge engagement with adjacent sides of the top coils of the two adjacent rows, the top coil of one of these two adjacent springs being disposed between the base of one loop and the bight of the companion loop, and through which bight the other loop passes, the base of said com panion loop passing through the top coil of the other of these two springs, said loops having formations for engaging the top coils of these two springs to prevent material approach or separation thereof whereby the rows of springs margined by the tie rods are maintained substantially parallel.

I will explain my invention more fully by reference to the accompanying drawings showing the preferred embodiment thereof and in which Figure 1 is a plan view of a wire mattress constructed in accordance with the invention, parts of the structure 'being removed as there is not sufficient space to dllustrate a mattress with a full complement of coiled springs; Fig. 2 is a view on line 22 of Fig. 1; Fig. 3 is a perspective view illustrating the manner in which the ends to opposite adjacent sides of the top coils of springs are a full, clear, concise,

adjacent springs in maintained in assembly; Fig. 4 is a perspective view illustrating the formation of a loop in one tie rod; Fig. 5 is a perspective view illustrating the formation of a loop in another tie rod; and Fig. 6 is a view on line 6-6 of Fig. 3.

Like parts are indicated by similar characters of reference throughout the different figures. i

Thewire mattress illustrated includes a rectangularframe 1. Coiled springs 2 are arranged in one row, coiled springs 3 are arranged in a row parallel to the row that contains the springs 2 and coiled springs 4: are arranged in a row parallel to the other rows of springs. These rows of springs extend longitudinally of the frame. The springs 2, 3 and 4 of the different rows are also arranged in rows. that extend transversely of the frame. These coiled springs are disposed perpendicularly to the plane of the frame, end coils of the springs being substantially in such plane. Substantially parallel pairs of tie rods 6, 7 margin opposite sides of the spaces between the rows that contain the springs 2, springs 3 and springs 4. These tie rods are secured at their ends to opposite sides of the frame 1 preferably by being wrapped around these opposite sides as indicated at 6 7 The tie rods 6 are shown as being formed with loops 8 that extend across from one row of springs (the row having springs 3 for example) to the adjacent row of springs (the row having the springs 2 for example), the base and bight of each loop 8 being respectively in hinge engagement with adjacent sides of the top coils of the two adjacent springs in adjacent rows. The bight 8 of each loop 8 is bent toward the plane of such loop to insure the maintenance of its hinge engagement with the coil end engaged by this bight. Each loop 8 has shoulder formations 8 near its base, the base parts 8 of each loop 8 being preferably substantially parallel with the main portion of the loop that extends between the rows of springs. The top coil of a spring has hinge engagement with a loop 8 at the corners formed by the parts 8 8 of such loop. The shoulders 8 cooperate with the bights 8 to prevent the coil ends engaged by the base and bight of each loop 8 from approaching to a material extent. The tie rods 7 are shown as belng formed with loops 9 that extend across from one row of springs (the row having springs springs -(the row having the springs 52 for example), the base andbight of each loop 9 being respectively in hinged engagement with adjacent sides of the top coils of two adjacent springs in adjacent rows. The top 'coil of oneofthese two adjacent springs is disposed between the baseS of loop 8 and the bight 9 of loop 9, the loop 8 passing through the bight 9 The base of the loop '9 passes through the top coil with which this base is in hinge engagement, this loop serving to prevent material separation of'the two 100 coils with which it is in hinge engagement owing to the manner in which its base is engaged with one spring coil and its bight is engaged with the other spring coils.

' Side stringers 10 have loops 10 by which the longitudinal side rows of coiled springs are anchored to the longitudinal sides of the frame.

Having thus described my invention I claim as new and desire to secure by Letters :Patentthe following A wiremattress including a rectangular frame; a plurality of coiled springs disposed perpendicularly to the plane of the frame and arranged in spaced apart rows that extend longitudinallyof the frame and which springs are also arranged in rows that extend transversely of the frame, end eolls of the springs'being substantially in the plane of the frame; and substantially parallel pairs of tie rods margining opposite loop, and through which bight the other loop passes, the base of said companion loop passing through the top coil .of the other of these two springs, said loops having formations for engaging-the top coils of these two springs to prevent material approach or separation thereof whereby the rows of springs margined by the tie rods aremain tained substantially parallel.

In witness whereof, I hereunto subscribelmy name this 11th day of December,
